1,5-二羟基蒽醌及其稀土配合物的红外光谱研究

STUDY ON THE INFRARED SPECTRA OF 1,5-DIHYDROXY-ANTHRAQUINONE AND ITS RARE EARTH COMPLEXES

利用同位素取代技术,并比较1,5-二羟基蒽醌及其稀土配合物的光谱变化,归属了它们的红外吸收带。确认了Ln—O键的特征带,分析了配位键的性质。

The infrared absorption bands of 1,5-dihydroxy-anthraguinone and its rare earth complexes have been assigned by using the isotropic substitution technique and comparing the changes among them. The characteristic absorption bands of Ln—O bonds were identified. The property of the coordination bonds has been analyzed.
